UNITED STATES PATENT OFFICE; BENJAMIN G. 'LAMME, or PITTSBURG, PENNSYLVANIA; AssIeNoR To WESTINGHOUSE ELECTRIC. & MANUFAo-rUmNeooMPA Y, a COR- i j PORATION OF PENNSYLVANIA.

Be it known that I, BENJAMIN G. 'LAMME,

a citizen of the United States, and a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Im rovement in Controlling Devices, of whic 1 the following is a specification. p I

j My invention relates to controlling means for translating devices that are ada ted to be opera-ted by either alternating or irect our:

The object of my invention is to provide systems which supply either alternatin or direct current energy to translatingdevices, with means for preventing the application of energy to either of two sets of controlling devices of an'amount or character for which it is not adapted.

vices have been constructed which may be operated bymeans of either alternating or direct current energy, and it frequently occurs that for economy in energy losses andv for'other .practical reasons it is desirable to employ controlling devices differing in char-' actor and construction according to the character of energy which is to be supplied through them. For instance, the voltageregulating devices for use with alternating current may comprise transformers the voltage ratios of which are variable, regulators having primary and secondary windings the 7 ing the supply of direct current to t 1e alterhating-current controlling; devices and for gerous to supply direct current.

and a direct-current generator' i delivers en-v ergy to conductors 5 and 6. Any suitable current-collecting devices, such as trolleys 7- andS, are adapted to make contact with the supply-conductors 2 and 3 andv 5 and 6, these devices bein connected, respectively, to terminals 9 and Terminals 1'2 and 13 of the switch 11 are reof a double-throw switch' 1.1.

spectively connected to contact-terminals 14 q and 15 of circuit-breakers 16 and. 17, the other terminals 18 and 19- of the circuitbreakers '16 and 17 being connected, res ectively, to the middle points 20 and 21 o inductive windings 22 and 23. Y

A non-inductive resistance 24 is connected 1 between one terminal of the inductive WlIlding 22 and one terminal of the tri ping-coil 25 of the circuit-breaker 16, the ot er termi-.

na-ls of the inductive winding-22 and the coil 25 being connected together and to one terminal of a non-inductive resistance device 26. The non-inductive resistance 26 is suitably subdivided bymeans of leads 27, that are respectively provided with contact-terminals 28, wit which apivoted arm 29is adapted to'engage, the-arm 29 being connected-to terminal 30 of switch 11 and to a terminal of the armature 31 of a motor 32.

One terminal of inductive resistance 23 and one terminal of tripping-coil 33 of cir-- cuit-breaker17 are connected together. One terminal of a non-inductive'resistance 34 is connected to the other terminal of the inductive resistance 23, and the remaining terminals of the coil .33 and the non-inductive resistance 34' are connected together and to one terminal of a transformer-winding 35,

the other terminal of which is connected to one terminal of the armature 31 of the motor-32.

Connected to a suitable point 36 interme diate the end terminals of the transformer- '3 I winding is one terminal of the secondary winding 37 of a series transformer 38, the other terminal of which is connected to a terminal 39 of a double-throw switch 40 with terminal 41 of switch 11 and with the middlc point of an inductive winding 42. The primary windin 43 of the series transformer 38 is connected b the double-throw switch 40, the terminal 46 of which is connected to a pivoted arm 47,

The devices just described comprisef'the means for varyin the alternatingecurrent e motor 32 but an other suitable means may be employed-,such, for example, as a voltage-regulator substituted in place of the series transformer 38, the voltage-regulator comprising primary and secondary windings the inductive relations.

of which are adjustable.

Anonsinductive resistance 50 is connected between one terminal of the inductive Winding 42 and that terminal of field-magnet" winding Slwhich is connected toeu terminal of the armature 31, the remainin terminals oi the inductive Winding 42 an the fieldmagn-et Winding 51 being connected. to ether. The operation of my invention may 6 unthet portion dfers tood from a consideration oi of the drawing which illustrates the directcurrent-controlling devices. If trotleys '7 and S-engegeconductors 5 and 6, res ectivedly, and switch 1:1 is in the; osi-tion's own, rect-current energy will Ye' suplied tothe motor- 32 through sup ly-eon uetor 6, trol- My 8,. terminals 10 ant 12 of switch 11,. and circuitbreeker 16, to the" middle" point of in ductive winding 22', When-e the current divides, the larger portion traversing section 52 the inductive resistance 22, to the non-ins smallerportion trstversing section 53 of the inductive resist-- amee 22, noiisi-ndnctive resistance 24 and coil: 25,. to the resistance 26 the circuit then cont tin'sfling through resistance 26, arr-n 29 meter oi switch 1 and trolley '7, tothe source 4.5- The-iur r portion of the current traverses the section 52 of the inductiveresistsnce 22, because of the greater ohmic resistance oi? the circuit through the portion 58, inductive r'e' j sistancei'e, end'vc'oil25. Theinrductive" resistancesiZZa-nd ZSeresu tenned because they possess very low ohmic- J; resistance, but have comparatively high in-;- ducti ve resistance when energized with alter=- noting current. The device 24 is so constructed as to have comparatively high ohmic resistance.
